Application filed my 25,

To all whom it may concern:

Be it known that we, LEWIS H. SWETNAM and Josnrrr MoonY, citizens of the United States, residing at Jacksboro, in the county of Jack and State of Texas, have invented new and useful Improvements in Radiator- Draining Means, of which the following is a specification.

Our present invention has for its object the provision of simple and convenient means whereby the operator of a Ford or other automobile is enabled to conveniently open the drain cock of the radiator and when necessary, clear the cock of sediment obstructing the same.

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof Figures 1 and 2 are views illustrative of the application of our improvement to a Ford automobile.

Figure 3 is a perspective of our improve- 'ment or attachment per se.

Figure 4 is a longitudinal section through the tubular rock shaft of the improvement and showing the cock-clearing pin or needle as removably sheathed therein.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The radiator 1 and drain cock 2 of the radiator may be and preferably are of the ordinary well known construction as is the chassis bar 3.

1 Among other elements my improvement includes a bracket 4:- The said bracket t is bolted at 5 to the bar 3, and is provided on. its rear portion with a clip 6, disposed below the bar 3 and adapted to straddle the lower portion of the same with a view to preventing lateral deflection of the bracket. The forward portion of the bracket 4 is inclined downwardly and forwardly and terminates in vertically disposed portion 7 in which is a transverse circular aperture 8.

In addition to the bracket 4 our improve ment comprises a tubular rock shaft 9 journaled in the bracket 4, and a needle or sharpened pin 10, headed at 11 and designed when removed from the tubular rock shaft to be used in clearing the bore of the cock, rovided the said bore is closed by sediment. he inner portion of the rock shaft 9 is bifurcated at 12 and is provided with a bolt 921. Serial 1l'o.48 7,429.

13 and nut 1% for the connection of the shaft 9 to the plug of therock. j

On its outer end the tubular rock shaft 9 is provided with an appropriate handle 15, and it will be noted that the said handle 15 is disposed at such a point that the operator may conveniently rock the shaft 9 to open or close the cock 2. In the event of the cock being plugged it is simply necessary for the operator to remove the pin 10 from its sheath in the shaft 9, and manipulate the pin to clear the passage through the rock. The said pin 10 may then be sheathed in the shaft 9 where it will remain by reason of frictional contact. Manifestly when not in use the pin 10 is conveniently carried where I it is out of the way and it is available for use when necessary. It will also be observed that the pin 10 does notinterfere in any measure with the manipulation of the rock shaft 9.

In order to preclude casual displacement of the needle or pin 10 from the rock-shaft 9, we provide a spring latch 16 on the latter to engage a circumferential groove 17 in the former.

Having described our invention, what we claim and desire to secure by Letters-Patent, 1s

1. The combination with the drain cock of an automobile radiator, of an appropriately supported rock shaft connected with the plug of the cock and extending to a point for convenient manipulation of the shaft; the rock shaft being tubular in form and provided with a handle, and, a needle with a head at its outer end being sheathed in the shaft and having its head disposed nor- 1 mally adjacent to the'ha-ndle of the shaft.

2. The combination with the frame and radiator drain cock of an automobile, of a bracket connected to and held against lateral deflection of one of the barsof the frame and having a transverse circular aperture, and a shaft journaled in such aperture and having a bifurcated inner end connected to the plug of the cock and also having a handle. on its outer portion; the said shaft being tubular and open at its outer end, and a pin being remova'bly sheathed in the shaft and extending through the open end thereof.

3. An attachment for automobiles comprising abracket adapted for connection to a chassis bar, and a tubular rock shaft j ournaled in the bracket and adapted for connection to the plug of a drain cock and open 10 at its outer end and having a handle at said end and also having a needle removably held Within it and projecting through its open end; the rock shaft being equipped with a, latch and the needle with a groove to receive the latch.

In testimony whereof We aflix our signetures.
